Crank arms come off easy post #1
My crank arms come off very easily... most crank arms stay on like a mother (especially WTP) but i can pull mine off with my bare hand (if the bolt is off). This might be because i just put WD-40 on the spindle (because of rust from my sprocket adapter). If my crank arm comes off this easily is it bad?

depends what cranks your running...
primo powerbites pretty much just slide right off...anything splined "should" be harder to remove...

my older profiles that i just got rid of around christmas time always used to come loose...and it was because over time they got stripped...the crank arm AND the spindle were stripped and wouldn't stay tight....which meant they always came off super easy and loose super easy.

but i just sent in my warranty and got a new pair.

no matter what 48 spline crank arms shouldnt just come off easily and that can be very bad since it doesnt have pinch bolts to clamp it on the splines will just strip so much easier and it doesnt matter if you put grease or oil on the spindle because i put grease on mine so that it wont rust to the spindle and they have been taken off many times now at least 8 times in the past 2 months and one arm i still cant take off its so hard

i like cranks with pinch bolts im still afraid of my 48 spline crank everytime i land i keep thinking its going to strip and break off the only thing i dont like about pinch bolt arms is the fact my pants are baggy and when pedaling fast they sometimes hang up on the pinch bolts and my foot gets pulled off the pedal but i like pinch bolts better still and easier to remove!! especially since my crank must of lost the crank puller in the mail or something and no one makes a crank arm puller the size that threads onto the arm

Don't worry about it. Cranks that don't come off easily piss me off anyway. I <3 used profiles.

ive never seen mosh make a 48 spline crank if you are talking about the ones with pinch bolts well yeah they are easy to take off because you loosen the bolts and slide it off but 48 splines dont have the pinch bolts to keep it tight so it has to be tight and hard to remove to ensure that it wont strip

think about it would you ride a crank with pinch bolts that were not tighten down? well this is the same for 48 spline cranks
